	该桥桥位处景色相当壮观，3座高桥在几乎同一位置跨越澜沧江，铁路拱桥，公路悬索桥以及中缅油气管线悬索桥。旁边的油气管线桥是世界同类桥梁中第四高的，仅次于巴布亚新几内亚的Hegigio Gorge管线桥，乌江油气管线桥以及瑞士的Niouc 管线桥。		该桥桥位处景色相当壮观，3座高桥在几乎同一位置跨越澜沧江，铁路拱桥，公路悬索桥以及中缅油气管线悬索桥。旁边的油气管线桥是世界同类桥梁中第四高的，仅次于巴布亚新几内亚的Hegigio Gorge管线桥，乌江油气管线桥以及瑞士的Niouc 管线桥。

-Due for completion in 2018, the stunning Lancangjiang Railway Bridge is the centerpiece of a new line between the cities of Baoshan and Dali in western Yunnan Province.  The new railway bridge crosses the upper reaches of a reservoir that was formed behind Xiaowan, the 2nd highest concrete dam in the world. The spectacular 958 foot (292 mtr) high double curvature structure holds back a body of water some 787 feet (240 meters) deep along the Mekong (Lancang Jiang), a river with several of the largest and highest hydroelectric dams in the world including the Manwan, Dachaoshan, Nuozhadu and Jinghong. The Mekong River is the only international river in Asia linking 6 countries. The river has more species of fish than any other waterway on earth except for the Amazon.  The full reservoir is 164 feet (50 meters) deep beneath the new railway bridge.

 Instead of using cable stays and tiebacks to build the arch, the two steel truss arch halves were built vertically on either side of the canyon slopes on top of scaffolding.  While still in a vertical position, the two halves were then then lowered down over the gorge where they were connected at the crown.  A highline was then used to build the vertical spandrel supports and road deck.  The total length of the bridge is 698 meters.

-The location has become a showcase for 3 high spans including an older suspension bridge, the new railway bridge and an even higher pipeline suspension bridge that is the 4th highest of its type in the world after the Hegigio Gorge Pipeline Bridge in Papua New Guinea, the Wujiang Pipeline Bridge and the Niouc Bridge in Switzerland.
